Produkteinführung

This side-discharge fan filter unit reorients the conventional ceiling FFU into a vertical cabinet for horizontal supply. The rear service section contains an EC centrifugal fan and prefilter, while the full-height front face holds the HEPA or ULPA panel and perforated diffuser. Adjustable feet or a wall frame support the assembly without consuming overhead grid space. The broad discharge face is useful for sweeping contamination away from low-mounted filling, inspection or packaging equipment that cannot be protected effectively by a downward ceiling module.

Key Features

The vertical filter face supplies a broad horizontal flow path directly across the protected work level.

A rear or top inlet can be selected to suit wall clearance and local return-air direction.

Internal equalising baffles reduce the velocity gradient between the fan centreline and cabinet edges.

Adjustable levelling feet and wall anchors stabilise the tall cabinet while leaving the front face unobstructed.

Kunden Produktbedenken

Some processes need clean air across the working plane rather than from above, especially where machines or services occupy the ceiling.

A dense overhead service zone leaves no clear ceiling bay for a conventional FFU.The vertical cabinet moves the fan and final filter to the wall or floor line while preserving filtered supply.

Downward air is blocked by tall equipment before it reaches exposed product surfaces.Horizontal discharge enters at process height and sweeps directly across the critical work zone.

A small outlet jet creates turbulence and dead corners along a wide production line.A full-height HEPA face and diffuser distribute airflow across a larger lateral area.

Tall freestanding modules can move or tilt during filter service.A wide base, levelling feet and optional wall restraint provide stable installation and repeatable alignment.
